'WHAT WILL IT TAKE TO ESTABLISH AN AUTHENTIC WESTERN BUDDHIST DHARMA?' - BEST ANSWER

One Western person must attain full enlightenment in the same way as Marpa, Milarepa, or Guru Rinpoche [Padmasambhava, Indian founder of Tibetan Buddhism]. If one Westerner—man or woman, doesn’t matter—attains that level of realization, then pure dharma will be established in Western culture, Western language, and environment, and so forth. Until that time, dharma can be taught in the West, which is already happening; it can be practiced in the West, which is already happening; and it can be recited in Western languages. But it’s not yet one hundred percent complete. Only with the presence of great mahasiddhas like Guru Rinpoche, Marpa, and Milarepa did dharma become established in Tibet. After that, dharma flourished within its own culture and language and has lasted to this day.   -  Tai Situpa
